Firefox, AIM, MSN and how the three of them keep fucking up

[Evil Sadistic Bastard]

My comp's been on the blink for a while now - I get randomly booted on and off AIM and MSN, and sometimes my Firefox goes a bit haywire.

AIM problems - frequently logs me in and out over and over and over again, resulting in a lot of lost responses.

MSN problems - as AIM, with the added problem of any transfer over 5MB or so suddenly cancelling halfway. THis makes it VERY hard to receive PDFs from my overseas friends.

Firefox troubles - sometimes I can access a certain site, then when I access another one in a tab or alternate window, it tells me that the first "can't be found". Usually, I have to wait a while before refreshing the first site and then it shows up.

Does anybody know what's wrong with this? If you need more information, pelase feel free to ask me.

It might be caused by your internet connection cutting out. Something similar used to happen to me when my router was overheating.

Somthing like that happened to me once, then I said screw it and switched to YIM, but ya like Destrucionater said your interned might be cuttin out

Have you ran all the usual spyware/malware scans? More importantly, it could simply be your ISP is doing maintenance on their servers lately and it's screwing you up a little.
